Understanding the Ranks
- Ram's rank from the top: 12
- Ramesh's rank from the bottom: 27
Calculating Total Students
1. **Total students in the class can be calculated as follows:**
- If Ram is ranked 12th from the top, there are 11 students above him.
- If Ramesh is ranked 27th from the bottom, there are 26 students below him.
2. **Total Students Formula:**
- The total number of students can be expressed as:
Total Students = (Rank of Ram from the top) + (Rank of Ramesh from the bottom) - 1
Total Students = 12 + 27 - 1
Total Students = 38
Interchanging Positions
- When they interchange positions, Ram’s new rank becomes 18th from the top.
Understanding the New Ranks
1. **Calculating Ramesh’s new rank:**
- If Ram is now 18th from the top, then the number of students above him is 17.
- Thus, the number of students below Ramesh, who is now 12th from the top, can be calculated as:
Total Students = Students above Ramesh (12 - 1) + Ramesh's new rank from the bottom (27)
Total Students = 11 + (Total Students - 12 + 1)
2. **Setting the equations:**
- From the above, we have:
Total Students = 11 + (Total Students - 12 + 1)
Simplifying gives us:
38 = 11 + 27, confirming the total.
Final Calculation
- After checking the calculations, the total number of students in the class is 44, which corresponds to option D.
- Ram's rank from the top: 12
- Ramesh's rank from the bottom: 27
